<h3>Description</h3>
<p>Thank you for implementing <a class="issue-link js-issue-link" data-error-text="Failed to load title" data-id="667225596" data-permission-text="Title is private" data-url="https://github.com/kamailio/kamailio/issues/2413" data-hovercard-type="issue" data-hovercard-url="/kamailio/kamailio/issues/2413/hovercard" href="https://github.com/kamailio/kamailio/issues/2413">#2413</a>, I'm looking forward to use it.</p>
<p>I was trying it on a dev system. It works fine when the same TLS client needs to be selected for ALL connections.</p>
<p>Having issue with it when connection expected to alternate between multiple configured TLS clients.<br>
When configured as bellow and event_route alternates between connections (like in logs bellow) connection is always using TLSc with one of the server-ids, e.g. "domain-02".</p>
<p>It looks like it's a race between setting server id in event_route and a "thread" that starts TLS client. In my observations only one TLS client is used.</p>
<p>Expecting: each outbound connection use TLSc as it was set by tls_set_connect_server_id().</p>
<pre><code>event_route[tm:local-request] {
if (is_method("OPTIONS")) {
$var(contact) = "Contact: <sip:" + $fd + ":5061;transport=tls>\r\n";
append_hf("$var(contact)");
if ($fd == "domain-01") {
tls_set_connect_server_id("domain-01");
xlog("L_INFO", "ID=$ci|tls_set_connect_server_id(domain-01)\n");
} else if ($fd == "domain-02") {
tls_set_connect_server_id("domain-02");
xlog("L_INFO", "ID=$ci|tls_set_connect_server_id(domain-02)\n");
}
}
}
</code></pre>
<p>Dispatcher configured as:</p>
<pre><code>loadmodule "dispatcher.so"
modparam("dispatcher", "list_file", "/etc/kamailio/dispatcher.list")
modparam("dispatcher", "ds_probing_mode", 1)
modparam("dispatcher", "ds_ping_interval", 60)
</code></pre>
